1. Be very very careful not to plagiarise - source all ideas!
2. Do not use any websites devoted to TOK essays (except this one)!
3. Do not google the titles as you will end up with the same ideas as thousands of other IB students!
Taken from the IB TOK PPF 2017:
You should explain why did you choose your Prescribed Title (PT) and what are your first ideas about it. Discuss how the TOK Launch Day workshops, the classroom discussions, and the meeting with your teacher helped you decide.
Use the planning document provided.
